平面显示器技术领域 BACKGROUND flat panel display

本发明涉及一种平面显示器， 尤其涉及需要大屏幕显示的场合。 The present invention relates to a flat panel display, particularly to a large-screen display as occasion demands.例如可应用于大屏幕壁挂式电视、 计算机大屏幕平面监视器、 室内外的大面积动态信息显示牌（如用于证券交易所的信息显示） 等。 For example, it may be applied to a large-screen wall-mounted television, large flat-screen computer monitors, large indoor and outdoor display board dynamic information (e.g., stock information for display) and the like.本发明也可适用于轻便的小型显示屏（如家用电器、 仪表的信息显示） 。 The present invention is also applicable to a portable small display (such as household appliances, the display information instrument).背景技术 Background technique

平面显示器可分为液晶显示器， 等离子显示器， 电致发光显示器和电致变色显示器。 The flat panel display can be divided into a liquid crystal display, plasma displays, electroluminescence displays and electrochromic displays.例如电致发光显示器和电致变色显示器是在玻璃基板上一层层蒸镀或涂布成膜， 再用刻蚀的方法加工出电极和发光单元。 For example, an electroluminescent display and a electrochromic display layer is coated or vapor deposition on a glass substrate, and then etching processing method of an electrode and the light emitting unit.显示器的尺寸受到基板大小和工艺的限制。 The size of the display is limited by the size of the substrate and process.显示元件采用电致发光(EL)元件或电致变色元件（ ECD )。 An electroluminescent display element (EL) element, or an electrochromic device (ECD).其工作原理为在电致发光材料或电致变色材料薄膜的两面分别采用干法（如蒸镀）或湿法（如电镀或涂布）制作两个导电层， 其中一个导电层为透明导电层。 The working principle is in both sides of the electroluminescent material or an electrochromic material films were dry method (vapor deposition) or wet (e.g., plating or coating) Preparation of two conductive layers, wherein the conductive layer is a transparent conductive layer .通过这两个导电层向显示材料薄膜施加电压或电流， 则在透明导电层一侧有可见光发出（电致发光）或有反射光的颜色亮度发生改变（电致变色）， 由此实现信息显示。 With these two conductive layers of the display material film applied voltage or current, the transparent conductive layer side of the visible light emitted (electroluminescence) luminance or color of reflected light is changed (electrochromic), thereby realizing an information display .

由于厚度薄、 体积小、 重量轻， 平面显示器已成为国内外厂商开发的重点。 Since the thin, small size, light weight, flat panel displays have become the focus of development of domestic and foreign manufacturers.目前各种平面显示产品的结构都以基板为基础， 在基板上用涂布、 蒸发工艺和刻蚀或印刷工艺形成发光单元阵列（象素） ， 各单元由纵横排列的平行导线驱动。 Currently a variety of flat display structure of the product to the substrate are based to form a light emitting cell array (pixel) coating, etching or evaporation process and printing process on a substrate, each unit is driven by a vertical and horizontal array of parallel wires.由于受蒸发和涂布工艺的限制， 显示器的尺寸难以做大。 Due to the limit evaporation and coating process, it is difficult to enlarge the size of the display.发明目的 Object of the invention

首先，参照附图的图1A - 1C和图2对本发明的一个实施例作详细说明。 First, with reference to the accompanying drawings FIG. 1A - 1C and 2, one embodiment of the present invention described in detail.图1A - 1C中示出了本发明带状显示元件1的详细结构。 FIG 1A - 1C shows a strip 1 of the present invention, a detailed configuration of a display element.图2中示出了由导电带2和本发明的显示元件1构成的一种显示器10的结构。 FIG 2 shows a structure of a display element by a conductive strip 2 and the configuration of the present invention to a display 10.

图中， 帶状显示元件1为夹层结构的扁平带， 由正面的透明导电膜5和背面的背面导电层4将发光或显色材料层3夹在中间构成。 FIG, 1 is a flat strip-like display element with a sandwich structure, a transparent conductive film 5 and the back surface of the back surface of the conductive layer or the light emitting front 4 chromogenic material constituting the intermediate layer 3 is interposed.整个显示元件外形为条状的薄带。 The entire display element shape of a strip ribbon.其中， 将要与导电带（电极）接触的背面导电层4为非连续结构， 其上以基本上相等的间距贯穿有宽度极窄的横向缝隙6， 因而成为沿显示元件的长度方向排列的互相绝缘的块状区域结构， 以使相邻的背面导电层4的各块状区域之间彼此绝缘。 4 is a discontinuous structure wherein the back side conductive layer, to be in contact with the conductive strip (electrode), which is substantially equal to the transverse distance through extremely narrow gap width of 6, and thus become insulated from each other along the longitudinal direction of the display element array the block structure of the region, adjacent to the back surface of the conductive layer insulated from each other between the respective block regions 4.另外， 缝隙6中也可以填充有绝缘材料以加强绝缘性。 Further, the slit 6 may be filled with an insulating material to enhance the insulating property.标号2为导电材料构成的导电带， 导电带为条状的导体薄带。 Reference numeral 2 is composed of a conductive material conductive tape, a strip of conductive tape strip conductor.

图2中的显示器为平铺排列结构。 FIG 2 is a tiled display arrangement structure.当显示材料较硬， 制成的带状显示元件不易编织时， 采用这种结构较易实现。 When the display harder material, strip-shaped display element made easy knitting, easier to achieve this configuration.彼此平行并且以基本相同的间距配置的显示元件1以其背面导电层与同样是彼此平行并且以基本相同的间距配置的导电带相接触的方式直角交叉， 由此构成显示阵列， 每一交叉点都是一显示单元（或称象素） 。 Substantially parallel to each other at the same pitch and configuration of a display device 1 with its back surface in the same conductive layer are substantially parallel to each other and at the same pitch of conductive strips arranged in contact with right angle, thereby constituting the display array, each intersection It is a display unit (or pixel).驱动电路分别接条状显示元件和导电带。 Driving circuits are connected with the conductive member and the strip-like display.当透明导电膜接地， 背面导电层接驱动电压时， 背面导电层的横向缝隙6保证了显示只发生在背面导电层通电的区域内。 When the transparent conductive film is grounded, then the back of the driving voltage conductive layer, the back side conductive layer 6 transverse slots ensures that only occurs in the display areas of the backside conductive layer is energized.显示元件的透明导电层和导电带为显示阵列（象素） 的纵横选址电极， 电流由透明导电层5经电致发光薄膜或电致变色薄膜3 , 背面导电层4流至导电带。 Transparent conductive layer and the display element is a conductive tape display array (pixel) aspect of the address electrode, a current thin film electroluminescent or a transparent electrically conductive layer 5 through the electrochromic film 3, the back side conductive layer 4 flows to the conductive tape.

导电带同帶状显示元件背面导电层之间可以采用粘接或焊接保持两者之间的接触（导通） 。 Conductive strips may be employed with the strip between the back surface of the display element bonded or welded to the conductive layer to maintain contact between the two (conducting).

显示元件1可以采用电致发光(EL)元件或电致变色（ ECD )元件。 Display element 1 may be an electroluminescent (EL) element or electrochromic (ECD) element.在电致发光材料或电致变色材料薄膜的两面分别采用干法（如蒸镀） 或湿法（如电镀或涂布）制作两个导电层4和5 , 其中导电层5为透明导电层。 Both sides of the electroluminescent material or an electrochromic material, respectively, using a dry film (vapor deposition) or wet (e.g., plating or coating) prepared two conductive layers 4 and 5, wherein the conductive layer 5 is a transparent conductive layer.通过这两个导电层向显示材料薄膜施加电压或电流， 则在透明导电层5—侧有可见光发出（电致发光） 或者反射光的颜色亮度发生改变(电致变色） ， 由此实现信息显示。 The conductive layer through these two material film applied to the display voltage or current, the visible light is emitted (electroluminescence) luminance or color of the reflected light is changed (electrochromic) 5--side transparent conductive layer, thereby realizing an information display .

图3A为本发明另一个实施例的结构示意图， 该结构使用了一种编织结构,这种编织方式使得显示元件交错排列。 FIG 3A is a schematic configuration of another embodiment of the present invention, the structure using a braided structure, this weave causes the display elements are staggered.带状编织工艺蒸发或涂布只需在窄的帶状材料上进行， 而且可以连续加工。 Evaporation ribbon weaving or coated only in a narrow strip of material, and may be a continuous process.由于编织工艺的固有特性可以使编织连续进行。 Due to the nature of the knitting process allows continuous knitting.因而， 通过生产长幅的显示元件可达到生产大屏幕显示器的目的。 Thus, by producing a long web display element can achieve the production of large-screen display.

为实现这一编织结构， 本实施例使用了图3B中所示的导电带的结构。 To achieve this woven structure, the structure of the present embodiment uses a conductive tape shown in Figure 3B.导电带2由二层结构构成， 一面导电另一面绝缘， 图中的7为导电面， 8为绝缘面。 2 is constituted by a conductive tape layer structure, the other side face of the insulating conductive, FIG. 7 is a conductive surface, an insulating surface 8.编织时要使导电带2的导电面7与显示元件1的背面导电层接触（导通）构成显示单元， 或者使导电带2的绝缘面8与显示元件1的透明导电膜接触。 For the conductive tape is knitted conductive surface 2 constituting the display unit 7 and the back layer in contact with the conductive (on) a display device 1, or the conductive surface 2 with the insulating transparent conductive film 8 in contact with the display element 1.为了保证帶状显示元件之间的绝缘以及导电帶之间的绝缘要控制元件的宽度和厚度及编织时的密度。 In order to ensure insulation between the strip-shaped display elements and the insulation between the conductive strips to control the width and thickness of the element and the density at the knitting.

图4为编织结构的另一种实现方式。 4 is another implementation of the woven structure.该实施例中， 显示器由显示元件、 导电带和绝缘线组成。 In this embodiment, the display by the display device, the conductive strip and insulated wires.其中9为绝缘线， 绝缘线为条状的绝缘体薄带。 9 wherein a strip of insulated wire, the insulated wire insulation strip.经向为间隔排列的条状显示元件和绝缘线， 纬向为间隔排列的导电带和绝缘线。 Via conductive strip and insulated wire display element and the insulated wire, the weft arranged at intervals of spaced strips.导电带同条状显示元件背面导电层之间形成欧姆接触， 间隔排列的绝缘线保证导电带之间的绝缘和条状显示元件之间的绝缘。 Conductive strips form an ohmic contact with the stripe display layer between the back surface of the conductive element, spaced insulated wire to ensure insulation between the insulating member and the conductive tape between the display strip.

在图2所示的平铺结构显示器的基础上， 用绝缘线9将显示元件和导电帶通过编织组合在一起， 如图所示。 On the basis of the structure of the display tile shown in Figure 2, the insulated wire with the display element 9 and the conductive tape by weaving together, as shown in FIG.调整导电帶、 条状显示元件和绝缘线三者之间的宽度比例可以调整条状显示元件的利用效率。 Adjustment conductive strip, the strip width of the display elements and the ratio between the insulated wire can be adjusted three stripe display element efficiency.当显示元件受到周围的电磁场影响时， 利用中间包有导线的绝缘线编织在显示元件的周围形成屏蔽， 控制电磁场的影响。 When the display element is affected by the surrounding electromagnetic field, using the tundish lead wire insulated wire braided shield formed around the display device, the control of electromagnetic fields.

本发明的显示器可采用多种显示元件， 如电致发光元件和电致变色元件。 Display of the present invention may employ a variety of display elements, electrochromic elements, such as electroluminescent elements and electrically.由于显示元件为分离的帶状元件， 故在没有合适的窄光语显示元件时可通过在具有白色发光光语的带状显示元件外加滤色膜实现彩色显示。 Since the strip-like display element is a separate element, it may be displayed through the display element color filter element is applied in a strip-shaped color display having a white light emission in a language not suitable narrow light language.

另外， 在本发明的实现中可以采用透明的导电帶， 将背面导电层做成透明的， 则可以实现上述器件的背向或双面显示应用。 Further, in the present invention may be implemented using transparent conductive tape, the back surface of the conductive layer is made transparent, or may be achieved away from both surfaces of the display device applications.

所有上述的实施例只是对本发明的说明， 而不是对其进行限制。 All of the above embodiments are merely illustrative of the present invention, and not in limitation thereof.本领域的熟练技术人员可对其进行变更和修改。 Those skilled in the art that variations and modifications may be made thereto.例如， 当显示材料很薄时， 条形显示元件的各导电层及导电材料可依次做在透明的有机基材上， 在这种情况下条形显示元件的组成结构为： 透明基材、 透明导电层、 电致发光或电致变色材料层、 背面导电层。 For example, when the display material is thin, the bar display of each layer and the conductive material of the conductive member can be done sequentially on a transparent organic base material, in which case the bar display is composed of structural elements: a transparent substrate, a transparent a conductive layer, an electroluminescent or electrochromic material layer, the back side conductive layer.其中， 对于背面导电层， 由于导电层为薄膜状， 当膜的厚度大大小于像素间的距离时， 若导电层的电阻满足以下条件， 即从导电带到需要发光像素的电致发光或电致变色层的电阻较小， 从导电带到不需发光像素的电致发光或电致变色层的电阻很大， 则可以采用连续的背面导电层。 Wherein, for the back-surface conductive layer, the conductive layer is a film-like, when the distance between the pixels is much smaller than the thickness of the film, if the resistance of the conductive layer satisfies the following conditions, i.e., from the conductive to the electroluminescent pixel requires electroluminescent or electrochromic lower resistance electrochromic layer, from the conductive to the pixel without electroluminescent or electrochromic layer resistance is large, the back surface of the continuous conductive layer may be employed.此时由导电层的阻值特性可保证发光区域是在所需区域。 At this time, the resistance characteristics of the conductive layer may ensure a desired region in the light-emitting region.
